BACKGROUND Field of the Embodiments

These embodiments relate generally to devices and methods for styling hair.

Background

Various devices for styling hair have been known for many years. The use of styling devices for curling hair has been known for many years in the form of hair rollers. The curling hair rollers come in various shapes and sizes and are manufactured from a variety of materials, from porous spongy materials to rigid plastic or metal materials. The curling hair rollers can be secured using a variety of devices such as various clamps, mesh caps, and fabric encasings.

Many users wear curling hair rollers throughout the night in an effort to create longer lasting curls and to prevent having to restyle the hair the following morning. Traditional curling hair rollers are hard plastic and uncomfortable to sleep on. To address this problem, there has been several curling hair rollers created to allow the user to sleep on the roller. However, none of these devices address the problem of being able to straighten hair or dry hair while sleeping.

Many users want their hair to be straight and non-frizzy. Presently, devices for straightening hair or eliminating frizz use high heat or harsh chemicals to straighten the hair to the user's satisfaction. However, these devices are very damaging to the hair.

Presently there are no hair styling devices with the desirable characteristics of eliminating frizz from the hair, styling the hair as desired, drying the hair as desired, and the ability of the user to wear the hair styling devices for an extended period of time without discomfort including while sleeping.

Accordingly, there is a need in this art for novel hair styling devices that can dry the user's hair while sleeping comfortably and style it without frizz, either imparting curls or straightening the hair. The instant embodiments address these needs and provide other advantages as well.

In some embodiments, the semi-compressible core comprises 100% polyurethane. The shape, size, and porosity of foam materials used for the semi-compressible core are not limited to the above materials, but are selected for specific characteristics including semi-rigidity, softness, low-moisture absorption, and the ability to style hair straight or curled. The smooth layer of the hair styling device surrounds the semi-compressible core and is made of suitable microfibers such as microfibers comprising polyesters, polyamides, polypropylenes, nylon, trogamide, para-aramid synthetic fiber, meta-aramid synthetic fiber, aliphatic polyamide synthetic fibers, and the like and equivalents thereof. In some embodiments, the smooth layer of the hair styling device comprises non-synthetic fibers such as cotton, bamboo, hemp, modal, wool, and the like and equivalents thereof. The shape, size, and combinations of fibers used for the smooth layer are not limited to the above materials, but are selected for specific characteristics, including softness, water absorbency, ability to wick moisture, and the ability to eliminate frizz and prevent hair breakage. The smooth layer of the hair styling device, including the strap described herein have nominal seams, threads, or bumps obtained through the use of a technology such as serging, heat sealing, or a similar technology, allowing the hair styling device to style the hair without any frizz or imperfections and to prevent the fabric edges from fraying.
